As an active member of the Arizona Repubican Party I will tell you that we were in shock. Everyone, including the Democrats assumed the SCOTUS would do their jobs because it is so clearly unconstitutional. A Congresswoman even gave up her seat and declared she was going to run for Senator because she thought she would be redistricted out of her seat. However, based on the decisions that came out before the redistricting, it took away some of the shock. Once you have a Supreme Court that doesn’t use the Constitution, all you have left are political lawyers. And that’s where we are.
SCOTUS has now handed the Democrats the very tools they need to smash the last bulwark against total Lib domination...the ability of Republicans to gerrymander a Congressional majority.
Between the redistricting case and the “disparate impact” housing case (minority Democrat voters coming to a safe GOP district near you) the process of CHANGE will be complete within a decade or so.
